Car & Classic boosts reporting speed 10x and saves 8 hours/week with Snowflake, dbt Cloud, and Metaplane

The problem

Car & Classic's two-person data team struggled with slow MySQL query performance, fragmented and uncentralized data definitions, and deteriorating trust in data quality, preventing stakeholders from reliably using data for decision-making.

First attempt

The previous approach relied on massive nested queries in Metabase and manual SQL re-writing from scratch each time, producing redundant metric definitions and bugs in production.

dbt Cloud data modeling
integration
“With the dbt Cloud IDE, we have a consistent environment where everything is the same.”
2
Metaplane automated monitoring
trigger
“After a 15-minute setup, the platform has been automatically monitoring their data.”
3
ML-based anomaly detection

“Another interesting discovery was brought to James' attention because of Metaplane's ML-based monitoring strategy. Over time, the distribution of auction prices changed in a way that was not consistent with seasonal changes.”
4
Proactive data incident alert
output
“Metaplane proactively alerted James' team about an anomalous decrease in the volume of website log data.”
5
Downstream impact and stakeholder notification
human_review
“James' team leverages Metaplane's downstream impact analysis to make every alert actionable. For example, James has received alerts regarding important data that is operationalized by the marketing team; he can immediately notify the team”
Reported outcome

After implementing Snowflake, dbt Cloud, and Metaplane, Car & Classic achieved 10x faster report load times and saved 8 hours per week on data incident identification, with the data team now proactively catching issues before stakeholders notice them.
